What Are Ice Dams and Why Are They Formed?
The attic is a part of the house that is typically under-appreciated and is known as an awkward space for storing junk. Surprisingly for most homeowners, the attic plays a big role in controlling the entire house temperature, acting as a ventilation system where the excess heat within the house rises into the attic.
Many newer-modeled homes are beginning to insulate attics to decrease the heat and energy loss. Having an uninsulated attic can lead to several problems, including the formation of an ice dam.
Ice Dam Buildup
An ice dam is a build up of ice at the base of the roof along the gutter, caused by melted snow that refreezes. A pool of water from melted snow develops and the longer this pool of water sits, the more time the water can find cracks in your roof. The major reason behind the ice dam occurring is a combination of poor attic ventilation and the snow acting as an insulator.
Attic & Snow Duo
Uninsulated attics in the winter can be problematic, especially during heavy snowstorms. After a heavy snowstorm, the bottom layer of snow begins to melt due to the roof’s heat. When the underside of the roof in the attic is higher than 32 degrees, the snow melts, running down the roof. If your gutters are not given proper care, the water then builds up, causing water to sit and eventually form to ice. After another big snowstorm, the process repeats itself, leaving more water to sit behind the ice build up. When there is little time between snowstorms, the snow becomes a powerful insulator, making the outside of the roof’s surface warmer and melting the snow faster.
Ice Dams can be extremely problematic for homeowners, and the damage is not always noticed right away. The sitting water on the roof seeps into the cracks of the roof, getting into your attic and walls. The most common ice dam effects are ceiling cavities and peeling or blistered wall paint. There is also the chance of mold and mildew formation. The attic insulation can be affected as well, which creates recurring problems for the interior and exterior of the house.
Ice Dam Prevention
You can take immediate actions to avoid ice dam formation. After each snowfall, a roof rake can be used to clear snow from the first three to four feet of your roof. Making sure your gutters are clean is another simple way to take immediate precaution when avoiding the chance of ice buildup. While these are just two short-term steps, there are also long-term ice dam prevention steps that will tackle the root cause of the issue. Insulating your attic and installing a water repellent membrane are two possible long-term solutions, but should be done by a professional.
